Thanks @SeriousHoax for the information and explanation.Well, I contacted F-Secure through the beta program and got a reply within a few hours.
1) The Rainbow Six Siege issue is known to them. F-Secure injects code into it, and apparently the game doesn't like it and refuses to start. I think most third-party AV products injects code into most processes, and usually the AV company and the game developers works together to come up with a solution to not cause any incompatibility. F-Secure hasn't done that it seems. They have asked me to submit the exe file explaining the issue in details. I'll do that and see what happens. Maybe they'll skip injecting code into it based on certificate whitelisting? I don't know...anyway,
2) Turns out F-Secure's game mode relies on Windows's own game mode. Game mode is enabled by default on Windows and when it detects a game it automatically enables it for the game. When Windows does that, F-Secure also enables their game mode. According to them, they tried to do the full-screen detection method for activating game mode, but that caused problems for them and didn't receive positive feedbacks. So they've chosen to go this route. This is a pretty good idea IMO.
There's gonna be some games where Windows's Game mode won't activate, but it's very easy to enable that for that particular game.
Here are examples:
i) Run a game then press "Windows Icon + G" to access Game Bar, press the settings icon there to see whether game mode has been activated for the game.
If it Windows recognizes the game, then it'll look like this.

Here I'm playing the game "Death Stranding" and Windows has detected that and activated game mode automatically. Which means F-Secure's game is also activated. In this case you won't have to do anything.
ii) Here I'm playing Telltale Games, Game of Thrones - Season 1 the game. Windows hasn't detected it as a game, so game mode hasn't been activated.

All you need to do is to access game bar again by pressing "Windows Icon + G", click the settings icon and tick the option "Remember this is a game". From now on Windows will always activate game mode when this game is run meaning F-Secure will do the same too.
You can do it for literally any programs whether it's a game or not.
I am going to test the game mode with some Blizzard games.
